Book Synopsis Carbon and Nutrient Dynamics in Natural and Agricultural Tropical Ecosystems by : L. Bergström
Download or read book Carbon and Nutrient Dynamics in Natural and Agricultural Tropical Ecosystems written by L. Bergström and published by . This book was released on 1998 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil fertility is one of the most important factors regulating yield and productivity in both the agricultural and natural ecosystems of the tropics, and maintaining soil fertility has become a key challenge to sustainable development in this region. This book presents the ecological processes and management practices which affect soil fertility and then looks at ways to integrate this knowledge to develop economically feasible solutions. Based on a symposium held at the University of Zimbabwe in May 1996, the volume is partly the result of ten years of research by the Soil Biology and Fertility Project in Zimbabwe and includes contributions from researchers in Africa, Asia, Europe and North America. The book is divided into five sections covering nutrient dynamics in soil, decomposition of crop residues, tree-soil-crop interactions in agroforestry and in ecosystem dynamics, and prospects for the future. Essential reading for agronomists, soil scientists and ecologists studying the tropics, this volume is also an important reference for decision-makers in land use and development in tropical countries.
Book Synopsis Dynamics and Diversity by : Ian Scoones
Download or read book Dynamics and Diversity written by Ian Scoones and published by Taylor & Francis. This book was released on 2010-09-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are critical to agriculture and, in turn, to food supply and livelihoods. Sustainable management of soils is crucial for a large proportion of the population of Africa. Contrary to many claims, soil fertility is improved and managed successfully by small-scale farmers there. Careful studies from widely different areas reveal how closely bound up soil management is with complex social, cultural and ecological factors - requiring a far more subtly tuned approach to development policy and practice. This work is a study of how the context of livelihood systems has to inform development policy and practice.
Book Synopsis Ecosystem Ecology Research Trends by : Junying Chen
Download or read book Ecosystem Ecology Research Trends written by Junying Chen and published by Nova Publishers. This book was released on 2008 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem ecology is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. A major focus of ecosystem ecology is on functional processes, ecological mechanisms that maintain the structure and services produced by ecosystems. These include primary productivity (production of biomass), decomposition, and trophic interactions. Studies of ecosystem function have greatly improved human understanding of sustainable production of forage, fibre, fuel, and provision of water. Functional processes are mediated by regional-to-local level climate, disturbance, and management thus ecosystem ecology provides a powerful framework for identifying ecological mechanisms that interact with global environmental problems, especially global warming and degradation of surface water. This book presents the latest developments in the field from around the world.

Book Synopsis Measuring and modelling soil carbon stocks and stock changes in livestock production systems – A scoping analysis for the LEAP work stream on soil carbon stock changes by : Food and Agriculture Organization of the United Nations
Download or read book Measuring and modelling soil carbon stocks and stock changes in livestock production systems – A scoping analysis for the LEAP work stream on soil carbon stock changes written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-01-14 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to build consensus on methods to measure and model soil carbon stocks and stock changes, the Steering Committee of the Livestock Environmental Assessment and Performance (LEAP) Partnership mandated a task force to develop this scoping analysis and pave the way towards the formation of the LEAP Tecnical Advisory Group on soil carbon stock changes. Soil carbon sequestration and storage in grasslands offers a significant potential to compensate for GHG emissions from livestock, but the lack of consensus on the appropriate methodologies to account for soil carbon stock changes hinders robust and standardized assessments. In this report, we reviewed several published soil organic carbon (SOC) models, and evaluated their aptitude to combine them with life cycle assessments (LCAs). Among contentious issues, the most relevant are: a) the lack of universal models, b) the uneven data availability, comparability and quality between countries and regions, and c) the difficulty to match measurable SOC fractions with those determined by the models. Taking this into account, a tiered approach is proposed, according to the availability of original data to run the models. The use of IPCC carbon (C) accounting system appears to be the simplest approach suitable to countries with scarcity of original C data. Conversely, more complex models such as Century (Parton 1987, 1988) or Roth C (Smith 1998) are likely to perform better and give less uncertainty when original input data are easily available.

Book Synopsis Organic Crop Production - Ambitions and Limitations by : Holger Kirchmann
Download or read book Organic Crop Production - Ambitions and Limitations written by Holger Kirchmann and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people believe that organic agriculture is a solution for various problems related to food production. Organic agriculture is supposed to produce healthier products, does not pollute the environment, improves the fertility of soils, saves fossil fuels and enables high biodiversity. This book has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues. An unbiased selection of literature, facts rather than standpoints, and scientifically-based examinations instead of wishful thinking will help the reader be aware of difficulties involved with organic agriculture. Organic agriculture, which originates from philosophies of nature, has often outlined key goals to reach long-term sustainability but practical solutions are lacking. The central tasks of agriculture - to produce sufficient food of high quality without harmful effects on the environment - seem to be difficult to achieve through exclusively applying organic principles ruling out many valuable possibilities and solutions.

Book Synopsis Managing Organic Matter in Tropical Soils: Scope and Limitations by : Christopher Martius
Download or read book Managing Organic Matter in Tropical Soils: Scope and Limitations written by Christopher Martius and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.
